Title: PVUSA, Photovoltaics for Utility Scale Applications: A national cooperative research project for directly harnessing the power of the sun to generate commercial quantities of electricity. Third quarterly technical report 1990

Technical Report ·
OSTI ID:10163243

Three of the five arrays planned for the project`s Emerging Module Technology Segment-1 (EMT-1) Davis procurement are in operation, along with one EMT host site array in operation on the island of Maui, Hawaii. The combined quarterly output for the four arrays was about 35,000 ac kWh, the same energy used by 23 average homes over the same period. Siemens Solar Industries has installed and interconnected the 3,968 modules that make up their 174 kW system. PCU and switchgear installation is scheduled for October. PVUSA began wet megger testing the array in September, but many panel bypass diodes failed the wet megger test. Siemens will do a field retrofit to the bypass diodes by resealing each with an RTV sealant. System start-up is now forecast for late October. Chronar and IPC began installing their US-1 structures this quarter. Chronar erected a 27-ft by 40-ft prototype ``building block`` test structure in July and IPC completed most of its foundation and support structure work in August.
